Procedure

259 mg (0.50 mmol) of 2-(2-((3R,5R,6S)-5-(3-Chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxo-1-(pentan-3-yl)piperidin-3-yl)acetyl)hydrazinecarboxamide (Example 76, Step A) was suspended in 2 N aqueous sodium hydroxide (16 mL) and heated at reflux for 3.25 h. Upon cooling to room temperature, the mixture was acidified with conc. HCl until strongly acidic and then extracted with EtOAc (3×). The combined organic layers were dried over
